To all whom it may Concern:

Be it known that l, Pmmlonn l?. Srnnr, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois` have invented'new and useful lnk provenients in Radiator Cores, of which the following is a specification. .I

, This invention has. relation to a radiator for an internal combustion engine di 'the Water cooled type, and it refers particularly to the core construction of such radiator.

The object of my invention is the provision of means forA increasing the cooling,r capacity of the radiator. A further object is to provide a simple, durable end inexpensive structure of the type mentioned. .,With these objects in View my invention consists in the novel combinations end important 'features hereinafter fully explained and Eli illustrated in the appended drawing, of which:

' Fig. l is a fragmentary front elevation of a radiator oore embodying the invention,

Fig. 2 illustrates e 'subdivision oi `.l

one of the composite members of the eore,

Fig. 8 is a frsgmpentary'side elevation of the structure shown in Fig. 2, f

Fig. Il is a cross sectional end View oi Fig. 3, taken substantially on line i-i.

Fig. 5 is a cross sectional elevation or one of the water channels of the core,

Fig. G'shows the water channel, and is taken on e line 6 6 of Fig. 5, and

Figs. 7, 8 and 9 illustrate e. portion or e spacing structure mounted Within each oi the members shown' in Fig. 2.

AS viewed from the front or the rear the radiator core is of a hexagonal cellular type, and .it is noticed that the passage through the cells is more or less obstructed by series of peaked projections 'formed 'hy the insertion of the spacing mernhers of Figs. 7, d, 9, the purpose of which will sppeer presently. rlike Water channels ere 'produced by assembling side by side e plurality of lthe frames of Fig. 2. y Estela of said Jrrarnes cornprises s peir oi corrugated strips and 2, which strips may he ersetly' alike in general outline, but ere placedzfreletively end for end, whereby each top sa'roee l. oi? one strip is positioned opposite the bottom surface 9. of the other. The strips l and 2 are suitably combined et the' top and bottom by lock seams 3 and Il. Nowit isnoticed, by referring to Figs. 3 and l that the strip. "l, end

similarly the strip 2.-'i;s e thin piece out metal Eler'ial Ho. 5283?@1.

from the hottoin1 ot' which, lb, rises univ foi-inl); spared indentations terminating in the top surfaes la. Along the edges it is seen that these indentstions are much enn lsrged, so as to form the semihexegonal "sends l. l (and 2C, 2d). ln the bottom snreoe of the strip is provided, adjacent to' said hand indentations, two series of semipherical protuoerances le, if. f

As hereinhefore mentioned l place a spe@ ing member 5 Within each Water channel freine l, 2, :ind it is noticed that this spacing member 5 is made with semihexagonal bends elong its side edges, the oppositely Adirected top surteees 'of .Whieln indicated hythe numersls', 5", csused to abut the bottoni surfaces lb, 2b' of the Water channel i'rornes, tlierelly completing the hexagonal cellular structure. The middle portion of the strip 5 is formed to'present a similar semiliexagonel hond, ont it is notioed that the corrugetions 5 in reversed relation tothe side eorrngstions il, 5h. 'intermediate this middle hond ond the two edge hands is found psir of narrow bends, the metal of whieli is termed into a iner sew tooth shape, there being about three teeth to each hexegonsl eorrugstion. The reeson for, and purpose of this construetion is twofold. ln the rst piece it would not oe commercially @possiole to roll or stamp the strip into the shape of the three mejor hands in the manner shown, heceuse the inetel would loe torn to pieces. Ent assuming! the shape to have heen produced,

the result would loe that the relatively opposite corrugetions oi' the midv die bend would he pleceddirectly behind the corrugetions o' the edge bends and that they 'would loloolr the sir passages through the outer oorrugetions, and thereby prevent the sir from -fiowing through the core.

ln the structure presented the sir entering; from the iront through e corrugeti'on 5b tiret strikes e. tooth with the result that it is detleeted or spread around and past said tooth end eronnd the peak 5 of the :dined middle eorrugstion, Alhe air then glides along the beveled surfaces 5B, 5f, tinelij; to strike the teeth 5g, whereupon it again is deiiected upward and downward, around the eorrngstions of the resr bend. An examination off the structure of Fig. 5, in connection with the foregoing description. will show that the air passing through the core, end lieingz. split 'spend variously directed., will strike the sides oi' the Water vchannels with great torce. Talre, for example, rthe air entering alone the three point ed arrow C. Thisf air will rst strike the tooth 5g, then slide ott and strike'allthree "sides of the Water channel corrngation.

It is Well known that, the more thoroughly the air can be out up, deflected in various directions and thrown against the water channel sides,fthe more complete will he the ,cooling 'operation' also. In the foregoing .l have presented a very eieient structure. and Il have also succeeded in 4solving/a very diticult problem, that namely of devising a wa f of equalizing the strain on the metal 'incldent to the operation ot' forming the strip into the shape shown,

In order to maintain'the water channels in alinement with the spacers during the operation 'of assen'ibling the core and prior to the usual soldering operation, I have provided tw'o series of buttons, 5, 5l, extruded from the metal of the spacers, and these bnr,- tons tit Within the protuherances l, lf ot' the water channel sides.

I claim:

1. In a radiator core, the combination With a series of corrugated water channels, of a similarly corrugated spacer lixed hetween each pair of water channels, said spacer made with a pair olf edge hands and a. center hand, all three of which are of the same shape but the corrugations ot the cen-- ter band are reversed relative to those ot the edge bands, there being more finely corrugated hands intermediate said center and edge bands.

2. In a radiator core, 'the combination with semihexagonal water channels, ot' a spacer mounted between each pair of channels, said spacer havingsimilar semihexagonal edge bands and middle band, the latter in reverse relation to the former, and made with a pair ot' finer toothed bands intermediate the said three hands.

3. In combination, Water channels and i,475,eos

spacers, all having semihexagonal edge hands combining to form a hexagonal rellnlar core, each spat-er having a reversed seinihexagonal middle hand and haring' narroW strips ot sanv tooth shape between the center hand and the said edge hands.

4. In a radiator core, a series ot' vertically disposed rectangular trames, the sides olt each trame long ot seinihe'agonal -contour and made right and lett. whereby the right side-of one i'raine terms a water channel with the left side of the next following traine and a spacer occupying the space Within each frame, said spacer havingsemi hexagonal edge yhands the vertical sin-fares Yot which alout the vertical sin-laces ot said sides, the spacer havingl a similar middle hand in reverse relation and made with saw vtooth bands intermediate the middle and the edge bands.

5 In a radiator core. rectangular trames having vertically disposed semihexagonal sides, spacers mountable within the trames and haring edge hands combining with said sides to torni a hexagonally cellular core,

Cil

said spacers having' a semihexagonal middle band in reversed relation tothe edge hands, there being finely corrugated portions permitting the metal'to be drawn into theI re-V verse relationaforesaid, the abutting snraces of the spacers and the traine sidesprovided with intertting aligningbosses.

In a radiator core, a spacer made iroin a thin strip of metal divided into three sul stantialiy equal bands of hexagonal ontline, except that the center band is formed in. reverse relation7 there'being two narrow intermediate bands of a finer saw tooth shape, whereby the metal ot said inter-nie diate bands is properly distributed in torining.

In testimony Wherot I have hereunto affixed my signature.
